Overall, the new sealing solution—in use since 2007—is outperforming the old method by a significant margin considering reliability, safety, energy and environmental perspectives. It increased pipeline flexibility and simultaneously improved overall product delivery.

This article will review properties from two basic tests, how they are determined and what value they have in selection of sheet-gasket material for an application.
The focus has been on the main source of the emissions—valve stem packing. Several companies have evaluated current industry standards and have crafted testing protocols specific to their application requirements.
You ultimately choose whether you send your used seals to the Seal OEM or to a non-OEM repair shop. Price and delivery obviously enter into the decision process. The trade-off, however, could turn out to be lower seal reliability and higher safety and environmental risk.
Galvanic corrosion is an electrochemical process that occurs between two dissimilar metals, or between a metal and a conductive non-metallic material, when both are exposed to an electrically conductive media.
Due to superior adhesion and other advancements, diamond coating technology is today being used in a wide range of sealing applications. The adhesion of new UNCD® Fface materials to their underlying silicon carbide rings is so high they can withstand loads that fracture the SiC without separation of the diamond from the SiC ring.
It is important to understand that pipe strain is one of the leading causes of premature pump failure. Pipe strain can cause "failure" of the packing or mechanical seal since they are both sensitive to misalignments introduced by pipe strain.
These steps will help ensure the best piping system performance for the longest time possible. When fewer gaskets are wasted due to deterioration from poor storage the result is additional money to combat real problems.
Although many of the energy costs of a shut-down can be difficult to quantify, they are numerous and substantial. Maintaining a process stream in operation increases its overall efficiency, while failures decrease it.
The oil and gas market has remained remarkably stable recently, bolstered by the high price of oil and strong worldwide demand. With refining capacity finite and political unrest in major oil producing countries such as Venezuela, Angola and Iran, the price may rise even higher.
